If you believe what mainstream medicine says then you probably believe you have delusional parasitosis instead of morgellon's.
Not to knock you down, but garlic has been proven to have anti-parasitic/bacterial/viral activity, so most definitely it would help in the case of morgellon's.
Medical journals can provide great information, if you know how to read between the lines that is...they (mainstream medicine) tend to twist it to work in their favor, not ours (to sell us their patented drugs).
